Cellular and molecular mechanisms underlying age-related skeletal muscle wasting and weakness

JG Ryall, JD Schertzer, GS Lynch - Biogerontology, 2008 - Springer
Some of the most serious consequences of ageing are its effects on skeletal muscle. The term
‘sarcopenia’ describes the slow but progressive loss of muscle mass with advancing age …

[PDF][PDF] The NAD+-dependent SIRT1 deacetylase translates a metabolic switch into regulatory epigenetics in skeletal muscle stem cells

JG Ryall, S Dell'Orso, A Derfoul, A Juan, H Zare… - Cell stem cell, 2015 - cell.com
Stem cells undergo a shift in metabolic substrate utilization during specification and/or
differentiation, a process that has been termed metabolic reprogramming. Here, we report that …

Role of β-adrenoceptor signaling in skeletal muscle: implications for muscle wasting and disease

GS Lynch, JG Ryall - Physiological reviews, 2008 - journals.physiology.org
The importance of β-adrenergic signaling in the heart has been well documented, but it is only
more recently that we have begun to understand the importance of this signaling pathway …

Functional screening in human cardiac organoids reveals a metabolic mechanism for cardiomyocyte cell cycle arrest

…, BS Launikonis, DE James… - Proceedings of the …, 2017 - National Acad Sciences
The mammalian heart undergoes maturation during postnatal life to meet the increased
functional requirements of an adult. However, the key drivers of this process remain poorly …

[PDF][PDF] Metabolic reprogramming of stem cell epigenetics

JG Ryall, T Cliff, S Dalton, V Sartorelli - Cell stem cell, 2015 - cell.com
For many years, stem cell metabolism was viewed as a byproduct of cell fate status rather
than an active regulatory mechanism; however, there is now a growing appreciation that …

Polycomb EZH2 controls self-renewal and safeguards the transcriptional identity of skeletal muscle stem cells

AH Juan, A Derfoul, X Feng, JG Ryall… - Genes & …, 2011 - genesdev.cshlp.org
Satellite cells (SCs) sustain muscle growth and empower adult skeletal muscle with vigorous
regenerative abilities. Here, we report that EZH2, the enzymatic subunit of the Polycomb-…

The orphan nuclear receptor, NOR-1, a target of β-adrenergic signaling, regulates gene expression that controls oxidative metabolism in skeletal muscle

MA Pearen, SA Myers, S Raichur, JG Ryall… - …, 2008 - academic.oup.com
β 1–3 -Adrenoreceptor (AR)-deficient mice are unable to regulate energy expenditure and
develop diet-induced obesity on a high-fat diet. We determined previously that β 2 -AR …

Therapeutic approaches for muscle wasting disorders

GS Lynch, JD Schertzer, JG Ryall - Pharmacology & therapeutics, 2007 - Elsevier
Muscle wasting and weakness are common in many disease states and conditions
including aging, cancer cachexia, sepsis, denervation, disuse, inactivity, burns, HIV-acquired …

[HTML][HTML] Comprehensive characterization of single-cell full-length isoforms in human and mouse with long-read sequencing

…, T Naim, A Chan, CH Ly, GS Lynch, JG Ryall… - Genome biology, 2021 - Springer
A modified Chromium 10x droplet-based protocol that subsamples cells for both short-read
and long-read (nanopore) sequencing together with a new computational pipeline (FLAMES) …

AMPK‐independent pathways regulate skeletal muscle fatty acid oxidation

N Dzamko, JD Schertzer, JG Ryall… - The Journal of …, 2008 - Wiley Online Library
The activation of AMP‐activated protein kinase (AMPK) and phosphorylation/inhibition of
acetyl‐CoA carboxylase 2 (ACC2) is believed to be the principal pathway regulating fatty acid …
